Heron Sato has been competing for 15 years. His best event is the Clock: a personal-best single of 4.41, set at CAU ao Cubo 2025, puts him in the top 3.1% of the 32,048 people who have ever been ranked in the event, and 13th in Brazil. Until June 2015, no official Clock solve in the world had been that fast. Across 77 competitions since July 2011, he has put 1,804 official solves on the record across 15 events.

His 3×3 best has come down from 24.63 in July 2011 to 13.49, a 45% improvement. Heron has entered 77 competitions, more competitions than 99% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

The story so far

Competitions

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
